Invoking component methods transiently using the cfinvoke tag

In ColdFusion pages or components, the cfinvoke tag can invoke component methods without creating a persistent CFC instance.

To invoke a component method transiently, use the cfinvoke tag and specify the following:

• The name or path of the component, in the component attribute.
• The method name, in the method attribute.
• Any parameters. For information on passing parameters, see Passing parameters to methods using the cfinvoke tag.
• If the component method returns a result, the name of the variable that will contain the result, in the returnVariable attribute.

To invoke a component method using the cfinvoke tag:

1. Create the following component and save it as tellTime.cfc:

   <cfcomponent>
   	<cffunction name="getLocalTime">
   		<cfoutput>#TimeFormat(now())#</cfoutput>	
   	</cffunction>
   </cfcomponent>
   

   The example defines a component with one method, getLocalTime, that displays the current time.

2. Create a ColdFusion page, with the following code, and save it in the same directory as the tellTime component:

   <h3>Time Display Page</h3>
   <b>Server's Local Time:</b>
   <cfinvoke component="tellTime" method="getLocalTime">
   

   Using the cfinvoke tag, the example invokes the getLocalTime component method without creating a persistent CFC instance.
